Chapter 1: Overview
The EtherHub 1500 System
The EtherHub 1500 System is a powerful and innovative LAN
network enhancement and management product series. Each
component in the system supports a multi-segment bus
architecture that enhances traffic management and network
bandwidth utilization. This system offers the network manager
a wide range of flexible configuration options, allowing you to
effectively increase your network’s bandwidth. In addition, the
entire installation can be monitored and controlled through any
network management station.
The major components of this network system include:
EtherHub-16mi
+
, a 16-port intelligent hub with an SNMP-
based network management agent for monitoring and
controlling various network components. It includes -
16 RJ-45 STP station ports for connecting computers to the
network using shielded or unshielded twisted-pair cable
1 optional port for installing an AUI, BNC or Fiber-Optic
module, which permits connection to thick or thin Ethernet
or 10BASE-F cable
2 FlexBus 1500 ports for connecting to compatible hubs via
a FlexBus 1500 STP cable
RJ-45 port 16 which can also be converted to a daisy-chain
port (
) using the daisy-chain switch
SmartWatch LED panel that provides an easy way to
configure and monitor the system
EtherHub 1500 System User’s Guide
1-2 Overview
In addition, this hub supports a multi-segment bus architecture
that enhances traffic management and network bandwidth
utilization. With an SNMP agent, this unit not only functions
as an intelligent hub, but can also monitor up to 10 intelligent
hubs connected to it (including itself) through the FlexBus 1500
port connection. The EtherHub-16mi
+
conforms to both the
IEEE 802.3 repeater specification and the Simple Network
Management Protocol (SNMP).
This hub supports both in-band and out-of-band management.
For in-band management, it uses Accton’s optional Network
Management Software, called AccView/Open (not included
with this package) to monitor and control a stacked system. For
out-of-band management, the device’s RS232 port can be
connected to a PC and managed using Accton’s EtherHub 1500
System Configuration Program. Any computer (i.e., XT, AT)
with a COM1~4 RS232 port, at least 640 KB on-board memory,
and a monochrome, EGA or VGA display can be used.
The Etherhub-16mi
+
can be configured as a stand-alone system
to form a simple LAN networking 2 to 16 computers using the
RJ-45 ports. Or it can be connected to other hubs using the
FlexBus 1500 port connection. Further network expansion can
be achieved using the BNC, AUI or fiber-optic trunk port
connection (optional ALT PORT), or the RJ-45 daisy-chain
port. Workstations are connected to the EtherHub-16mi
+
station ports using shielded or unshielded twisted-pair cable.
EtherHub 1500 System User’s Guide
Overview 1-3
EtherHub-16i
+
, a 16-port intelligent 10BASE-T hub. It includes -
16 RJ-45 STP station ports for networking computers to the
network using shielded or unshielded twisted-pair cable
(STP or UTP).
1 optional port for installing an AUI, BNC or Fiber-Optic
module, which permits connection to thick or thin Ethernet
or 10BASE-F cable.
2 FlexBus 1500 ports for connecting to compatible hubs or
to the EtherHub-16mi
+
via a FlexBus 1500 cable.
RJ-45 port 16 which can be converted to a daisy-chain port
(
) using the daisy-chain switch.
Comprehensive LED indicators on the front panel to provide
easy and quick configuration and monitoring the unit.
As an intelligent hub, the EtherHub-16i
+
collects port statistics
and records events for system administration. When stacked with
other intelligent hubs through the FlexBus 1500 ports and
connected to an SNMP management device (e.g., EtherHub-
16mi
+
), you can monitor and control all attached hubs through
in-band and out-of-band communication.
The EtherHub-16i
+
can be used in a stand-alone configuration
to form a simple LAN networking 2 to 16 computers using the
RJ-45 ports. Further network expansion can be achieved using
the BNC, AUI or fiber-optic trunk port connection (optional
ALT PORT), or the RJ-45 daisy-chain port. Workstations are
connected to the EtherHub-16i
+
station ports using shielded or
unshielded twisted-pair.
AccView/Open (SW6102), a Windows-based network
management software package that analyzes and displays data
from the EtherHub-16mi
+
and transmits commands from the
user to the EtherHub-16mi
+
. AccView should be installed on
the network management station (i.e., any workstation used to
manage the network). If segmented architecture is used, the
network management station should be on the same segment as
EtherHub 1500 System User’s Guide
1-4 Overview
the SNMP management agent (i.e., EtherHub-16mi
+
). The
network management station can be a 386 or 486 workstation
with a 10MB hard disk, at least 2 MB on-board memory, a
VGA display, and running Windows version 3.1 or higher (i.e.,
Windows 3.1, 3.11, ’95, NT).
AccView/Open EtherHub Manager, is network management
software specifically designed to manage Accton’s EtherHub
family. This software can be integrated into the following
third-party management platforms -
SunNet Manager/Sparc (SW6120-1)
SunNet Manager/X86 (SW6120-2)
OpenView/Windows (SW6121)
OpenView/Sparc (SW6122)
Novell Netware Managment System (SW6124)

Hardware Description
This chapter describes the hardware features of the EtherHub-16i
+
and EtherHub-16mi
+
. Except for 3 LED indicators that are unique
to each hub, both products have similar indicators and other front
panel components. Likewise, the rear panel is similar for both
versions, except that the EtherHub-16i
+
does not support the RS-
232 serial port. Before connecting any network device to the hub,
read this chapter carefully. For easier management and control of
the hub, familiarize yourself with the front panel indicators and
Configure button.

SmartWatch LED Panel
Both hubs have a SmartWatch LED panel that includes
comprehensive indicators for monitoring the device and
network status. A quick glance at the front panel tells you if
the unit’s power in ON, if it is monitoring another hub (or
concentrator), or if a problem exists on the network. The
following sections describe the function of each indicator.
